Photography of slit-lamp biomicroscopy combined with retro-illumination photography is the gold standard in cataract evaluation. However the application is limited due to its complexity and low efficiency. We introduce digital non-mydriatic fundus photography as a new method for cataract screening in patients with visual impairment,which might play an important role in screening low vision and blindness caused by cataract. Two distinguished benefits are found in this method including compatibility for tele-diagnosis,and integration with screening of glaucoma and diabetic retinopathy. Cautions should be made on the photographs in which media opacity derived from other than cataract or low quality photos due to small pupils.

Age-related macular degeneration ( AMD ) is the main cause of blindness in the people older than 50 years old. In recent years, following the improvement of imaging techniques in ophthalmology, the pathogenesis of the disease, the level of diagnosis and efficacy evaluation ability greatly improved. In this paper, we reviewed and discussed the recent advancement on imaging research of age-relate d macular degeneration.

Objective To observe the clinical efficacy of needle knife, Governor-Vessel moxibustion plus medication in treating ankylosing spondylitis (AS).Method Forty AS patients were randomized into a treatment group and a control group, 20 cases in each group. The control group was intervened by intravenous administration of Ossotide injection, while the treatment group was by needle knife and Governor-Vessel moxibustion in addition to Ossotide injection. Before and after the intervention, the symptoms and body signs, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and Bath Ankylosing Spondylitis Functional Index (BASFI) were observed in the two groups, and the clinical efficacies were compared between the two groups.Result The total effective rate was 90.0% in the treatment group versus 75.0% in the control group, and the between-group difference was statistically significant (P<0.05). After the intervention, the symptoms and body signs (spinal pain score, Schober test, morning stiffness duration, chest expansion degree, and occiput-wall distance) were changed significantly in both groups (P<0.05). The BASDAI and BASFI scores were significantly changed after the intervention in both groups (P<0.05). The BASDAI and BASFI scores in the treatment group were significantly different from those in the control group after the intervention (P<0.05).Conclusion Needle knife plus Governor-Vessel moxibustion and medication is an effective approach in treating AS.

Objective To evaluate preventive and therapeutic effects of low dose of unfractioned heparin on severe sepsis. Methods 52 Patients with severe sepsis hospitalized in Intensive Care Units were randomly divided into control group and heparin group. On the basis of conventional therapy, patients with sepsis were given low dose of unfractioned heparin or isovolume physiologic saline by continuous intravenous drip infusion over 5 days. Acute Physiologic and Chronic Healthy Evaluation (APACHE-Ⅱ) score, blood platelet count(BPC), prothrombin time(PT), activated partial thromboplastin time(aPTT), thrombin time(TT), plasma fibrinogen(FDP) and D-dimer levels were assessed on admission, 3rd, 5th day after intervention. Incidence of disseminated intravascular coagulation(DIC) and 28-day mortality between heparin group and control group were compared. Results There were no significant difference in APACHE-Ⅱ, BPC, PT, aPTT, TT, and FDP levels, incidence of DIC, and 28-day mortality between heparin group and control group. D-dimer levels in both groups decreased along with time. D-dimer levels on 5th day after treatment in heparin group was markedly decreased than that of control group(740?135?g/L vs 853?179?g/L, P

Objective To investigate the effectiveness of interventional therapy for the atherosclerotic renal artery occlusion (ARAO). Methods During the period of June 2001-Dec. 2007, 16 patients with ARAO (total of 16 occluded arteries) underwent interventional managements, including percutaneous endovascular renal artery revascularization, balloon dilatation angioplasty and stent placement. Follow-up survey was made at regular intervals. The patent condition of the renal artery was evaluated with ultrasonography and digital subtraction angiography. The blood pressure and the renal function were determined and the data were statistically analyzed in order to assess the intermediate and long-term effect of the interventional therapy. Results Of 16 patients, technical success was achieved in 15 (93.8%) and failure occurred in one. During a follow-up period of 9 - 24 months, 3 patients died. According to the data obtained at each patient’s last follow-up survey, the hypertension fell to normal in 3 (25.0%), was improved in 7 (58.3%) and showed no marked change in 2 patients (16.7%), with a clinical efficacy of 83.3% (10 / 12). The renal function was improved in 2 (16.7%), stabilized in 6 (50%) and deteriorated in 4 patients (33.3%), with an effective rate of 66.7% (8 / 12). Conclusion For the treatment of atherosclerotic renal artery occlusion, the interventional therapy carries high successful rate and can effectively lower the blood pressure level, in addition, it can also protect the renal function in a certain degree.

Objective To investigate whether the extact of ginko biloba (EGb761) can protect the retinal ganglion cells (RGC) after acute high intraocular pressure induced retinal ischemia-reperfusion injury. Methods Thirty Sprague-Dawley rats were randomly divided into three groups. The negative control group, positive control group, treatment group were given normal saline 5 mL/kg, 1% erigeron breviscapus (vant) hand-mazz (EBHM) 5 mL/kg, 1% EGb761 5 mL/kg, respectively 2 hour after injury and every day after operation. Retinal ganglion cells were retrograde labeled by injection of 3% fluorogold (FG) into both side of superior colliculus 5 days before the death of the rats. Results The average survival rate of retinal ganglion cells were 61.46%, 72.73% and 76.20% in negative control group, positive control group and treatment group respectively. Conclusion EGb761 has neuroprotective effect on retinal ganglion cells in acute high intraocular pressure induced retinal ischemia-reperfusion injury.

Objective To investigate the efficiency of three methods to detect HPV infection of desquamated cervical epithelial cells and the relationship between methods and TCT.Methods hC2 method was used in disconnecting the HPV DNA chain in the samples to hybrid captures,and examine the 13 types of HPV which were highly related to cervical carcinoma.Q-PCR was first used to extract HPV DNA of samples and expanded nucleotide to be examined on Q-PCR to obtain results directly.MPHC was used to extract HPV DNA and to amplify nucleotide.The products was added to micro-well plate to proceed hybridization,and enzyme label was added,and results were studied in the enzyme labelling apparatus.The results of the latter two methods were the same as hC2.hC2 matched Q-PCR was used to examine 260 eases of desquamated cells from HPV infection against 200 cases of desquamated cells from HPV infection,and the results were compared by using MPHC matching examination.Results 1.With three methods,HPV infection was found to be 100% in all the abnormal cervical squamous epithelial cells.2.The sensitivity of the methods,howerer,was different.The QFCR and MPHC had higher positive rate than hC2.Positive HPV infection rate with Q-PCR and MPHC was the same as that of hC2 in the majority of cases,as in a few cases,it was positive with Q-PCR and MPHC but negative with hC2 alone False positive rate was 2% in MPHC.Conclusion HPV testing combined with the TCT routine is the best screening program for detecting cervical cancer and precursor of cervical careinoma.
